Title:
8086:4238 [Lenovo ThinkPad T430 2347] Wireless network doesn't resume
after suspend/resume (sometimes)
Status in “linux” package in Ubuntu:
Expired
Bug description:
It seems that sometimes my wireless network interface disappears after
suspend/resume.
When this happens, listing hardware with lshw does not show the
wireless adapter.
Reloading the wireless kernel module drivers does not work!
The command I'm using to do that is the following:
sudo rmmod iwlwifi mac80211 cfg80211 ; sudo modprobe cfg80211 ; sudo modprobe
iwlwifi ; sudo modprobe mac80211
And finally (and this is quite weird to me), a "soft restart" of the
computer does not work! That is, selecting the "Restart" option from
the logout menu doesn't work. The last time this happened I tried a
"soft restart" 4 times and every time the wireless interface did not
come up. However, as soon as I did a "hard reboot" (selecting Shutdown
from the logout menu, waiting a few seconds and then starting the
computer again) fixed the problem right away.
This probably indicates that the wireless controller itself (hardware)
is in some undefined state.
I tried adding adding the following line to /etc/pm/config.d/config:
SUSPEND_MODULES="$SUSPEND_MODULES iwlwifi"
That has not solved the problem.
As I stated, I don't think this is happening every time I
suspend/resume, but when it happens I consistently need a "hard
reboot" to fix the problem and get my wireless interface up again. I
will do a few suspend/resume cycles later to try to see how frequently
this happens.
